La face cachée du transport routier !

Une étude menée par des chercheurs de l’université de Californie a permis de mettre en avant le coût énergétique caché du transport. En effet, on considère souvent uniquement le coût direct lié à la consommation mais ce n’est que très rarement qu’on prend en considération les coûts de fabrication et encore bien moins souvent les coûts liés à l’extraction des matières premières, à leur transport, etc.

Cela a permis par exemple d’observer que bien que les émissions de CO par personne par kilomètre parcouru (en anglais PKT) sont similaires en considérant la consommation pour la voiture, le train et l’avion, elles sont de l’ordre de 110 à 40 fois supérieures lorsqu’on prend en compte la face cachée du transport !

On peut également réaliser que les coûts énergétiques liés au transport aérien augmente de 30%, l’automobile de 40% et le train de 200% ! Cela reste à relativiser avec le fait que le train soit le moyen le moins gourmand lorsqu’on considère uniquement la consommation !

La prochaine fois que vous monterez dans votre voiture, j’espère que ce sera avec un petit pincement au coeur 😉
